Feature Enhancement Suggestion:
The histograms are useful, in that they show more than just the average value. However, when a pair for R & L are shown, the scales are not usually the same, making the comparison of right & left less helpful. For example in the Breaking G data below the L range is 7.0 to 11.7, while the R one is 5.9 to 9.0. Showing them both using a combined range of say 5.9 to 11.7 would allow for a more meaningful comparison.
